The Checkline TI-44NA Ultrasonic Wall Thickness Gauge accurately measures wall thickness and the extent of corrosion of all metals, ceramics, glass and most rigid plastics - from only one side!

The attractive, ergonomic housing design is extremely compact, lightweight and rugged. It fits comfortably in the palm of your hand and incorporates a back light that illuminates the LCD in poorly lit areas. This product is similar to our TI-45NA, however the probe is hard-wired to the gauge and is NOT removable as in the TI-45N.
